WINDOW- SPECIFICATION forming part of Letters Patent No. 507,755, datedOctober 31, 1893.

Application tiled April 15, 1892.

To all whom it may con/cern.'

Y Be it known that I, CHARLES W. RoDEoKER, of Maryville, Nodaway county,Missouri, have invented certain new and useful Improvements inWindow-Screens, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates first to screens for the 1o windows of dwellings,business-buildings, and various other similar structures, and secondlyto the sashes of such windows, and the objects of my vinvention are,first, to produce window-screens which shall be simple, strong,

durable and inexpensive in construction, and entirely automatic in theiroperation, and which shall be capable of application to all types ofwindows, and which shall be automatically extended and concealed .inconsezo quence of the raising and lowering of the window-sashes, andwhich, furthermore, shall in no way cause any disgurement or materialalteration in the structural features of the window frames or sashes;secondly, to z5 produce attachments forwindow-sashes which shall preventthe entrance of insects, dust, or other objectionable matters into theapartments, and which shall be capable of application to all types ofwindow-sashes,and which 3o shall, furthermore, be simple, strong,durable, and inexpensive in construction.

To the above purposes my invention consists in certain peculiar andnovel features of construction and arrangement, as herein- 3 5 afterdescribed and claimed.

In order that my invention may befully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 is an inner side elevation of awindow frame and its sashes withmy improvements applied thereto. Fig. 2 is a transverse vertical sectionof the same, on the line 2--2 of Fig. 1. Fig. 3 is a horizontal sectionof the same, on the line 3-3 of Fig. 1. Fig.4is

a detached perspective 'view of one of the screen-winding-rollers, itssupporting-brackets, and a portion of one of the screens. Fig.

5 is a longitudinal section of the same, on the 5o line 6-6 of' Fig. 4;the roller-actuating spring being shown as partly broken away.

In the said drawings, 1 designates the frame or casing of a window, saidframe or casing SCREEN.

Serial No. 429,249. (No model.)

being shown as of the usual rectangular form, and 2 designates the lowerand 3 the upper sash of the window; these parts being (excepting ashereinafter explained) of the usual or any preferred form and type ofconstruction.

4 designates a spring-rotated roller which is mounted horizontally inthe window-casing 1 just above the sill 5 thereof, and which is ofhollow cylindrical form, and of such length as to extend from one grooveto another in which the lower window-sash 2 works. At one end thisroller carries a cap r6 vwhich is riveted or otherwise secured upon theend of the roller 4, and from the middle of which extends a stud 7 theouter end of `Vsaid stud being inserted intoa bearing-opening 8 whichopening is formed in the lower part of a vertical bracket 9. Thisbracket 9 is secured upon the sill 5 at a point adjacent to the wall ofone of the grooves in which the lower sash' 2 works. Longitudinallythrough this roller 4 extends a rod 10 which is of such length as toextendfrom near the cap 6 to and through the opposite end of the roller.The outer end 1l of this rod is iiattened as shown and projects througha disk 12 so as to rotate freely in said disk. From the inner side ofthis disk project inwardly two anges 13 which are inserted intol notchesin the. corresponding end of the roller4, thus preventing the disk fromturning independently'ofAv the roller. Two external shoulders 14 and'15abut respectively against the inner and outer sides of the disk 12 andthus retain the rod in its proper position without interfering with thefree rotation of the roller 4. The flattened outer end 11 of the rod 10enters a recess 16 in a companion bracket 17, the said bracket beingsecured in vertical position upon the sill 5 adjacent to the oppositegroove from that occupied by the standard 9.

In order to prevent all possibility of accidental detachment of theflattened end 11 of the rod 10' from its bearing in the recess 16, apivoted stop 18 is preferably secured vupon the outer side of thebracket 17, and when in normal position, depends across the outer end ofthe recess, and also abuts against a stud 19 which also projects fromthe outer side of the bracket. `Thus the stop or guard 18 may be raisedwhen the end 11 of the rod is being inserted into the recess, and thenal- IOO lowed to drop so as to close the outer end of the recess andthus retain the end 11 within said recess, the end 11 ofthe rod beingmoved to the inner end of the recess of course, to allow the pivotedlatch to clear or pass said end 11, in its descent. A coiled spring 20surrounds the rod 10 and its inner end 21 is inserted into a transversegroove or notch which is formed in the inner end of the rod 10, whilethe outer end of said spring is suitably secured to the inner side ofthe disk 12. Thus when the roller 4 is rotated in one direction, thespring 20 is wound, and when the roller is released, the springautomatically unwinds and rotates the roller 4 in the reverse direction.A collar or cap 22 is riveted or otherwise similarly secured to thecorresponding end of the roller 4, as shown.

23 designates the lower screen section, the lower margin of which issuitably secured longitudinally upon the roller 4, and which is of'awidth corresponding to that of the lower sash 2. At its upper margin,this screen-section is provided with a bindin g-stri p 24 the ends ofwhich are bent inward so as to enter recesses 25 which are formed in thelower corners of the inner sides of the sash 2; the arrangement beingsuch that the ends of the binding-strip and the screen-margins shall tsnugly between the inner side of the sash and the inner bead of thewindow frame or casing 1. Three, or any suitable or preferred number, ofloops 2G of wire or other suitable material, are secured to thebindingstrip 24 and are engaged with a corresponding number of nails 27,or equivalent devices, which are driven into the lower rail of the sash2. Asemi-cylindrical shield or guard 28 is secured to the sill 5 andextends upward and outward so as to conceal the lower roller 4 and itsattachments; said shield being of sheet-metal, or other suitablematerial, and corresponding in length with the width of the lower sash2.

From the above description, it will be seen that when the loops 26 areconnected to the nails 27, the lower screen-section 23 will be unwoundfrom the roller 4, as the lower sash 2 is raised; this unwinding` ofsaid screensection rotating the roller 4 so as to wind the spring 20.Then the lower sash 2 is lowered, the spring 20 will unwind andconsequently the lower screeirsection 23 will be wound upon4 the roller4.

In the upper part of the window-frame 1 just above the top-rail 29thereof, is mounted horizontally a second roller 30 to which is attachedthe upper margin of the Lipper screensection 3l. This roller` 30 in allrespects is the saine as the roller4 above described, and is alsoprovided with caps 6 and 22, a rod lO, spring 20, and the otherattachments the same as said roller4; the ends of the binding-strip 24of this upper screen-section and the margins of said screen section,working between the inner bead of the upper sash 3 and said sash, asbefore described. Thus it will be seen that when the upper sash 3 islowered, the upper screen-section 31 will be unwound from the roller 30;winding the spring 20 of said roller. When the upper sash 3 is raised,the spring 2O of the upper sash will be unwound and will so rotate theupper roller 30 as to wind the screen-section 31 thereon. Consequently,in both the upper and lower sashes, the opening which is formed byraising or lowering the sashes is covered by the screen-sections, andall insects are excluded from the apartment. The upper-*roller 30 isusuallyconcealed from view by the usual Window-curtain, but if desired,a shield or guard 28 (similar to the shield or guard 28, abovedescribed) may be used to conceal said upper roller, as indicated inldotted lines in Fig. 2. In order to exclude dust, dirt, and insects fromthe room, a flexible strip 32, such as rubber or the like, may besecured to the ,upper bead 33 of the window-casing, and extend outwardover the roller 30, so as to close the space between the roller 30 andthe toprail of the Windowframe. In order to further prevent theentranceof dust, insects, dac., into the apartments, a strip 34, also offlexible material, is secured to the under snrface of the lower rail ofthe upper sash, and the inner margin of said strip abuts closely againstthe outer surface of the pane of glass in said sash, so as to rubclosely upon said pane when the sashes are moved.

From the above description it will be seen that I have producedattachments which are simple, strong, durable and inexpensive in andsecured thereto at one end,the combination of a cap 22 secured upon oneend ot' the roller, and having an inwardly extending flange at its outerend and a disk l2 mounted loosely upon the said rod 10 and bearingagainst the inner side of the cap 22 and against the inwardly extendingflange thereot', and having inwardly extending flanges'l adapted toengage recesses in the end of the Abody-portion 4, of the annularshoulders 14 and 15 bearing upon the inner and outer sides of the disk12, to retain said rod in its proper position longitudinally,Substantially asset forth.

[n testimony whereof I aix my signature in the presence of twowitnesses.
